See LICENSE.TXT for details.##===------------------------------------------------------------------------===### This file is included by all of the LLVM makefiles. This file defines common# rules to do things like compile a .cpp file or generate dependency info.# These are platform dependent, so this is the file used to specify these# system dependent operations.## The following functionality can be set by setting incoming variables.# The variable $(LEVEL) *must* be set:## 1. LEVEL - The level of the current subdirectory from the top of the# source directory. This level should be expressed as a path, for# example, ../.. for two levels deep.## 2. DIRS - A list of subdirectories to be built. Fake targets are set up# so that each of the targets "all", "install", and "clean" each build# the subdirectories before the local target. DIRS are guaranteed to be# built in order.## 3. PARALLEL_DIRS - A list of subdirectories to be built, but that may be# built in any order. All DIRS are built in order before PARALLEL_DIRS are# built, which are then built in any order.## 4. Source - If specified, this sets the source code filenames. If this# is not set, it defaults to be all of the .cpp, .c, .y, and .l files# in the current directory. Also, if you want to build files in addition# to the local files, you can use the ExtraSource variable## 5. SourceDir - If specified, this specifies a directory that the source files# are in, if they are not in the current directory. This should include a# trailing / character.## 6. LLVM_SRC_ROOT - If specified, points to the top of the LLVM source tree.## 8. PROJ_SRC_DIR - The directory which contains the current set of Makefiles# and usually the source code too (unless SourceDir is set).## 9. PROJ_SRC_ROOT - The root directory of the source code being compiled.## 10. PROJ_OBJ_DIR - The directory where object code should be placed.## 11. PROJ_OBJ_ROOT - The root directory for where object code should be# placed.## For building,# LLVM, LLVM_SRC_ROOT = PROJ_SRC_ROOT##===-----------------------------------------------------------------------====## Configuration file to set paths specific to local installation of LLVM#ifndef LLVM_OBJ_ROOTinclude $(LEVEL)/Makefile.configelseinclude $(LLVM_OBJ_ROOT)/Makefile.configendif## Include all of the build rules used for making LLVM#include $(LLVM_SRC_ROOT)/Makefile.rules
